Hi,
I'm running X86 FS model, it would take me a long time for starting a FS model. I find it just using
one CPU, can gem5 use more CPU when running FS model?
No. It's modeling a whole complex system at the level of individual small
steps of each component in the system, done using a single event queue.
Given that each event could in principle affect the any other units,
things pretty much have to be done in order.
One might be able to build a concurrent simulator for multiprocessors,
but gem5 is not that simulator - and it would not be an easy task to
get much speed up. Imagine, for example, when each cpu gets access to
a bus, or its possible need to react to cache misses coming from other
cpus, etc.
